To all whom it may concern:

Be it known that I PHILIP J. Rrvsns, a citizen of the United tates and a resident of New Rochelle county of Westchester, and

State of New York, have invented certain new and useful Improvements in Car-Axles of which the following is a full, clear, an exact description.

This invention relates more articularly to axles for railway cars in whic one wheel is fixed to the axle and the other wheel is adapted to rotate independently of the axle to overcome friction and bindin of one wheel with relation to the other w ile turnin curves. I I

leretofore it has been plroposed so far as I am aware, to provide e axle with one wheel'fixed and the-other loosely mounted thereon in order that. one wheel-may rotate about the axle when the I car is moving around curves and thereby overcome the binding efiect due to one wheel-necessar ly having to rotate faster than the .otherwwhile making fturns. Such constructions-e have been impractical for the reason that the loose wheel has not been properly held "to the axle andrailroads havefailed to ado t the same for thereason that-they-areiliab e to accidents. .Some constructions provide bolts and similar fastening means, and others provide means forholding the loose wheel in such a way as'to beliablefto become loose or detached. It is necessary in axles f this kind that 'the loose wheel beiheldn a manner substantially" as rigid as .the' fixed wheel and that bothvwheels. should beheld so as to be impossible of detachment under ordinary use. it being.the '-lcommon Dractice to force the flxed-wheelon the tapered portion of the axle with many tons ofpressure in order that the-wheel cannot possibly become loose while in use.- i v The primary object of my invention-is toprovide simple and'etlieient means wherebyboth wheels may be apphed to the axle in substantially the same way-undersimilar pressure and .underl substantiall the'same. conditions'except-that one whee may have, an independent movement aboutthe-axl and at thesametime soflconstructing .an holding thewheels to the axle that ithesaid .whccls will underanormal conditions-move with; the i axle,-; and only a relativev dude heels while-turning curves w endentwrotaryil. movement .wglven I .to the b A furthe'r'object ofthe-inventiorr provide a simple and eflicient holding bushin V which may be made to form substantia y a part of the axle, and which is adapted to hold the wheel mounted thereon in as efiect'ive a manner as the ordinary fixed wlieel is attached to the other end of the ax e.

ith'these and other objects in view, the invention will be hereinafter more particularly described with reference to the accompanying drawings, which form a part of this-specification, and will then be ointed gut inthe claims at the end of the escripion.

In the drawings, Figure .1 is a sectional view, j partly in elevation, of one form of axle and wheels embodying my invention; and Fig.- 2 in a detail view of one form of bushingthat may be employed.

The axle 10 has enlarged portions 11 and IQ'mterinediate-its ends, and at oneend of the axle o's'a tapered ortion 18 and at its andabe t'ween thepartmandthe end 15 is, a "tapered portion" 16. This tapered portion 16 extends outward from the-part 12 and the said part 12 is faced" oil at 17 to provide a shoulder against which-the inner'surface of' 'the hub portion oft-the wheel 18 is adapted to rest.'- there being another wheel 'lllzrizidlv held to the tapered portion 13 of thela'xle' in the usual-wayn- A;busliina'-20 or steel or-anv other suitable-metal has a tapered opening 21 therethrouah. and said'bushintr is adapted to fit and, be rii'ridlv .held tofthe tapered portion 16 .ofth'e axle.--Thi sbushing or thimble has a straiirht cylindricalport 22 which is adapted tolit in a straight openine: 28 of tho-car wh'eel in-such a manner that the saidicar'wheel vm'av. have an independent 'rotary movement iahout the bushing The kbushmg at one-end improvided with an integral collar 24 vwhich isadapted to fit a recessed port1oni25 in'Tthe-.whee1=18 so as ,tO confine the "wheel .between the face 17 ofathetenlarged part 12and'said collar. At the 'inn'eriend the bushing. is somewhat reduced to :-lprovide-- a'iabendable =substantially cylindrica portionhQth: vThis part 20 may e ofany adesiredllenpzth and to permit the same to-bend withoutcrimping it may be provided with one or more slots, as 2'7, to

adapt the biishin g when forced along the tapered ortion 1 ofthe collar toenter a conical c aunel or "roove 28 in the enlar' d part 12 of the ax e 10 formed in the ace 17 adjacent to the inner portion of the ta)eredpart1 ti.- V n practice,"it is usual to force the car wheels on to the tapered part of the axle under many tons of pressure and if one of the wheelsis-to'be loose or have a relative movement, it should be done under substantially the same conditions asthe fixed-wheel and without anyefastening means that is liable to become loose while the invention-is in use. Thisis accomplished with myinvontion by having the thimble forced u on the tapered part-10' after bein place an the opening in the wheel 18 w: h a prommately the same pressure as the w eel 19 is forced on the other end of the axle, as the bushing is forced on the-tapered part 16 the bendable end 26 will enter the'goonical or tapering channel 28 of the axle and-be forced-inward as shown, thusservin further to bind and'hold'thebushing; o the axle and rigidlv rnountingthe" wheel 18 against'possible detachment at the same tune avoiding any accident that mightmccur by reason of suchwd'etachmentr While thelcar= is moving in a-right lme or straight'path,it is the intention that the two wheels should rotate with'the-axlezas wheel, t mer-1s,{wareanuts proper relative movementghctwecn the wheel'srand .the axle, which: under ordinary conditions.

may be very slight dof'that therelative-moves? w meat of the eo-called loose wheel will notin any case be eufiicient to'l cause much wear or friction between the frelat-ive moving surfaces. To, reduce this wear,"I'-have provided means for lubricating ,thebe'aring surfaces-Y between the wheelYfT18"'and' the bushing? though this lubricating ineans may bvaried and-the extent of the lubrication also mass 'as desired. Anyone ineansa slight'chan'nel ot ,'groove 29 is'jprovided emu the wheel 18 along the' opeiiing28' 2 thereof, orf along thebushing as preferredlfandian oil channel or opening:BO'leading'thereto extends at an;
